• Description: USB NAND Flash ROM error
• Causes: [9001] USB NAND Flash ROM cannot be read. • Defective controller board [9101] The ID of the USB NAND Flash ROM cannot be read. • Defective controller board [9110] The USB NAND Flash ROM controller is disconnected. • Defective controller board
• Remedy:

• Code: 840
• Description: EEPROM error 1: EEPROM access • During the I/O processing, a reading error occurred. The 3rd reading failure causes this SC code. • During the I/O processing, a writing error occurred.
• Causes: Defective EEPROM
• Remedy:

• Code: 841
• Description: EEPROM reading error. Mirrored data of the EEPROM is different from the original data in EEPROM.
• Causes: Data in the EEPROM is overwritten for some reason.
• Remedy:

• Code: 842
